Note: Performance results were measured using Microsoft NT Performance Monitor.
Measurements were obtained by measuring averages for the period of steady-state activity (i.e.
after 15, 000 users were successfully logged on). Tests measure the messaging throughput of a
single-server, single-site topology. For deployment-specific information contact a Microsoft or
Compaq representative. More information can be found at:
